AimsThis study examines clinical experience with methanol poisoning during a one-year period.MethodsAll admissions with the diagnosis of suspected methanol toxicity were analysed and the current guidelines for the management of this problem were reviewed.ResultsTwenty-four subjects were identified. Most had a history of chronic use of methylated spirits. Four died before admission to hospital and the other 20 patients had 26 admissions to hospital and form the basis for this report. Four patients died in the Intensive Care Unit. In total 11 patients were admitted to the Intensive Care Unit. Seven patients received haemodialysis. There was no correlation between the methanol level and the outcome. The strongest predictor of death or a poor outcome was a blood pH < 7.0. Some patients, in spite of potentially lethal methanol levels of up to 160 mmol/L, did not develop signs of toxicity.ConclusionsThe overall mortality was high and ethanol was given to most of the patients for up to several days. Some patients did not show any toxicity and some of those were not given ethanol. It is recommended that chronic meths drinkers, who are not acidaemic and are generally well, do not require ethanol treatment. Only the complete removal of methanol from methylated spirits will reduce the morbidity of this condition.
